Spirit's 1968 debut album spent more than six months on the Billboard album charts and received heavy airplay on underground FM radio. Their music was part of the core, essence, and heartbeat of the the hippie, psychedelic, counter culture movement. The album is timeless, as fresh today as when it first appeared. The band could play more styles than almost any other group. On Spirit they unveiled a mélange of rock, jazz, blues, folk-rock, and even a bit of classical and Indian music. The music is experimental. The vocals flow as easily as the instrumentals. Spirit struck a careful balance between disciplined studio chops, jazz improvisation, and driving rock and roll. Guitar prodigy Randy California is a clear standout, but the other band members are superb as well; John Locke's shimmering keyboards, Mark Andes' subsonic wall of bass, and Ed Cassidy's precision drumming. Big credit has to go to lead singer Jay Fergusson, whose phrasing is always just right with a wonderful spontaneous feel. The Marty Paich string arrangements are sublime.

Rock & roll had grown louder and wilder by leaps and bounds during the '60s, but when Blue Cheer emerged from San Francisco onto the national rock scene in 1968 with their debut album, Vincebus Eruptum, they crossed a line which most musicians and fans hadn't even thought to draw yet…

Live On The BBC is a 2004 hybrid CD by British hard rock band Deep Purple. Remastered by Steve Hoffman for Audio Fidelity and released on 20 January, 2004, this is a rip of the CD (redbook) layer, so it omits the bonus track on the SACD layer, "Lucille".

Musicmagic is Return to Forever's seventh and final studio album and one of the best jazz recordings released in the fusion genre. The album contains the final line-up of the band with only founders Chick Corea and Stanley Clarke returning from the previous recordings. This 1977 release was the first Return to Forever album in five years to contain vocals, performed here by Corea's future wife Gayle Moran and the surprisingly enjoyable Stanley Clarke. This album also marked the return of original member Joe Farrell on saxophone and flute, along with several new members making up a killer five-piece horn section.

Recorded in early 1975, Tale Spinnin', Weather Report's fifth studio album is filled with sunny textures of Latin and African flavors. During the '60s and early '70s Weather Report began to move towards a more cosmopolitan groove, and a melding of song with jazz in new and refreshing ways. The recording stands with anything recorded during the so-called "jazz-rock fusion" era, if only on the basis of the range of fresh, intriguing originals by the band's co-founders and principle composers, the keyboardist Joe Zawinul and the saxophonist Wayne Shorter. Zawinul's pioneering interest in what we now call world music is more in evidence with the exotic percussion, wordless vocals, and sandy sound effects of "Badia," and his synthesizer sophistication is growing along with the available technology. Wayne Shorter's work on soprano sax is more animated than on their previous albums and Alphonso Johnson puts his melodic bass more to the fore.

Leon Russell's accolades are monumental in a number of categories, from songwriting (he wrote Joe Cocker's "Delta Lady") to session playing (with the Rolling Stones and Bob Dylan, just to name a few) to his solo work. Unfortunately, it's the last category that never really attracted as much attention as it should have, despite a multitude of blues-based gospel recordings and piano-led, Southern-styled rock albums released throughout the 1970s. Leon Russell and the Shelter People is a prime example of Russell's instrumental dexterity and ability to produce some energetic rock & roll. Poignant and expressive tracks such as "Of Thee I Sing," "Home Sweet Oklahoma," and "She Smiles Like a River" all lay claim to Russell's soulful style and are clear-cut examples of the power that he musters through his spirited piano playing and his voice. His Dylan covers are just as strong, especially "It's All Over Now, Baby Blue" and "It Takes a Lot to Laugh," while "Love Minus Zero/No Limit" and "It's a Hard Rain Gonna Fall" have him sounding so forceful, they could have been Russell's own.

Joe Cocker! is Joe Cocker's second studio album, released in November 1969. Following the template of his first LP, this album features numerous covers of songs originally performed by Bob Dylan ("Dear Landlord"), The Beatles ("She Came in Through the Bathroom Window" and "Something" - both released almost simultaneously with original versions; "Let It Be" was also recorded and released as a B-side), Leonard Cohen ("Bird on the Wire"), and future touring partner Leon Russell ("Delta Lady"). Cocker also co-wrote one song, "That's Your Business Now", Chris Stainton, who was also his writing partner in later years.

Sometimes, a greatest-hits set is timed perfectly to gather together a group's most successful and familiar performances just at the point when that group has passed the point of their maximum exposure to the public, but before the public memory has had a chance to fade. That was the case when Columbia Records assembled this compilation for release in early 1972. At that point, Blood, Sweat & Tears had released four albums and scored six Top 40 hits, each of which is heard here. But lead singer David Clayton-Thomas had just quit the group, so that the unit that recorded songs like "You've Made Me So Very Happy" was not working together anymore. And even when Clayton-Thomas returned, the band would continue to decline commercially. As such, BS&T's Greatest Hits captures the band's peak in 11 selections–seven singles chart entries, plus two album tracks from the celebrated debut album when Al Kooper helmed the group, and two more from the Grammy-winning multi-platinum second album.

The follow-up to the breakthrough Headhunters album was virtually as good as its wildly successful predecessor: an earthy, funky, yet often harmonically and rhythmically sophisticated tour de force. There is only one change in the Headhunters lineup – swapping drummer Harvey Mason for Mike Clark – and the switch results in grooves that are even more complex. Hancock continues to reach into the rapidly changing high-tech world for new sounds, most notably the metallic sheen of the then-new ARP string synthesizer which was already becoming a staple item on pop and jazz-rock records. Again, there are only four long tracks, three of which ("Palm Grease," "Actual Proof," "Spank-A-Lee") concentrate on the funk, with plenty of Hancock's wah-wah clavinet, synthesizer textures and effects, and electric piano ruminations that still venture beyond the outer limits of post-bop.
